79 Exciter 440 (Yamaha)
I Just bought a 79 Exciter 440, i pulled the main bolt out of the clutch to replace the primary sheave, it was shattered in pieces. Anywho, i got the old clutch off and went to put the new one on and the main bolt wont screw into the crank all the way, it screws in about 4 turns then gets really tight. any chances when i removed that bolt that it messed up the threads? If so what size are these threads inside the crank so i can try and Tap them to straighten them out. If that doesnt work it looks like ill need a new crank. Any information would be appreciated.
